Is it better to do a tour or walk around by yourself self guided?

I enjoyed it by myself but guide is always a good. So you can get additional information.

Agreed. It also depends on how much time you have to dedicate to the area.

Depends on what you prefer. I was there to visit a specific person and i thought it more appropriate to walk by myself. But, if you would appreciate a guided tour, by all means.

Guided tours are far more informative
